What are the signs of a stress response in dogs?

Common signs of stress in dogs include vomiting, diarrhea, frantic licking of the tongue, self-biting, and incontinence; in severe cases a dog may even suffer seizures or die. When a dog is stressed, its immune resistance drops and the likelihood of other diseases increases. Owners should therefore avoid scaring their dogs and prevent stress triggers. If your dog is timid, keep the home free of loud noises and avoid rearranging furniture, as changes in the environment can cause stress.
